How many

  • People 1,028 people
  • Survey responses 1,566 records

Who is affected

  • Contacts at businesses that answered a next-generation power system survey

Cause

Answers from a 2013 METI survey were mixed by the same contractor into an Environment Ministry deliverable that was then published

  2. First disclosure

Response

  • Forensic investigation

The Environment Ministry is checking access; will report to the PPC if needed

What you should do

  1. Don't open links in emails from this company. The apology email itself may be fake
  2. Treat refund or apology calls and texts as scams. Call back only on the number from the official site
  3. Check the company's notice to see if you're affected

Lessons for companies

  1. Put security requirements, audit rights and reporting deadlines in vendor contracts
  2. Two-person review and pre-release tests for sharing and cache changes; monitor cloud config (CSPM)
  3. Report to the PPC: preliminary in 3–5 days, final in 30 (60 if malicious)
  4. Run red teaming and AI-assisted hardening, and publish how much you invest
